recently my zzr250 has been lasting about 30 minutes in traffic before getting really hot when i come to a standstill.... the temp gauge still hasn't gotten all the way to hot but it's boiled twice. could it be that my fan is stuffed?? i've cleared out the radiator, but i live in a dirt st so it still gets a bit messy. temp is fine once i get going but i can feel it on my legs when it gets too hot, regardless of what the gauge says. it was all good before i dropped it ... however i didnt bust the radiator or anything, i think i might have doen something when i took the frotn fairings off. any suggestions to keep it a bit cooler??
